
Measured values
In the dropdown menu, select which raw signals are available.
Based on the selection, the inputs for voltages or currents are displayed or hidden.

Show line-to-line
This option is only available in a star system.
It activates the additional inputs for U12, U23 and U31.
If the additional inputs are not assigned to any signals, the central unit will calculate
the signals and use them for the further calculations.
If signals are assigned, they will be the basis for calculations.

Nominal voltage
The nominal voltage for this grid, e.g.: 230 V

Mains signalling voltage
If this option is activated, the carrier frequency of the mains signalling voltage as
well as the percentage signal level needs to be set for the grid.
You can find out the carrier frequency at your local energy supplier. The signal level
usually lies between 1-2%.
